How BIG is your Footprint?
The measure of the total amount of harmful greenhouse-gas emissions that people produce, either directly or indirectly.
Review: Greenhouse gases cause the earth to heat up by trapping the sun’s heat in the earth’s atmosphere – acting like a greenhouse.
Common Greenhouse Gases produced by humans:
* One molecule of carbon dioxide (CO2 )has an atmospheric lifetime of 50-200 years. Since it is difficult to separate and quantify each distinct greenhouse gas, scientists commonly use CO2 to measure the global-warming problem.
The Carbon Footprint calculator measures the total amount of Carbon dioxide (CO2) and other greenhouse gases each person produces a year. A footprint is an impression you leave behind. Similarly, the carbon your daily decisions create are also left behind and accumulate.
Is carbon all bad?
Actually, it’s not. Our bodies are mostly made of carbon, as is just about everything we touch and see, from trees to diamonds. All life depends on carbon.
But carbon is also oil, natural gas, and coal — hence, its polluting connotation. When carbon in the atmosphere pairs with oxygen molecules that are created through the combustion of plants, dung, and fossil fuels, it becomes CO2. The current global atmospheric concentration of carbon dioxide is nearly 40 percent higher than levels in the air before the industrial revolution!1
Turns out, even your daily actions are pretty damaging to our earth….

The good news is, there is a lot you can do to minimize your footprint:
